Max Mosley is convinced another F1 manufacturer will pull out of the sport if the car industry continues to struggle.

Only four days ago, Honda caused a considerable shock by putting their team up for sale due to the economic downturn and a worldwide slump in car sales.

"I don't think F1 is teetering one way or the other in terms of bust or survival, but if things get worse in the car industry then it could be," Mosley said. "At the moment nobody can say we are seeing the bottom and that it will improve."

He added: "All the stock markets are up in the last two or three days, and they may think things are going to get better.

"They may be right, but then again they may be wrong. The thing is, we literally don't know.

"If things get better for the car industry, then that's fine, we are through the worst. We would just need to sort out Formula One.

"If things get worse, then our problems will get worse.

"But at present I haven't heard anything specific as to whether another manufacturer will pull out. Again, I don't think anybody knows.

"But if the situation does get worse for the car manufacturers then we will lose another one.

"Whether that would be before the season starts is difficult to say. We are in unknown territory."
